LITTLE ROCK (AP) — A former Republican candidate for sheriff in Faulkner County has been sentenced to one month in federal prison for transferring a false birth certificate as part of an effort to discredit another GOP candidate for sheriff.

Smith pleaded guilty to creating a false birth certificate showing that GOP sheriff’s candidate Andy Shock fathered a child in Texas in an effort to prevent Shock from winning the Republican nomination for sheriff. Smith also admitted to mailing the false birth certificate to voters in Faulkner County who it was thought would vote in the GOP primary.

Shock won the nomination and the general election in 2012 and is the current county sheriff.
